Be it enacted by the Senate and House of Representatives of the
United States of America in Congress assembled, That from and after
six months after approval of this Act no marriage thereafter entered
into, to which a member of the Klamath or Modoc or Yahooskin Band
of Snake Indians of the Klamath Indian Reservation in Oregon is a
party, shall be valid for any purpose unless such marriage shall have
been solemnized pursuant to the laws of the State in which the
ceremony is performed.

SEC. 2.

Bona fide Indian custom marriages with members of said
tribes mentioned in section 1 existing prior to the effective date of
section 1 of this Act are valid, and recordation of such marriage with
the superintendent of the Klamath Indian Agency, if both parties are
then living, in a book kept by him for that purpose shall be prima facie
evidence of such marriage. The nonrecordation of such a marriage
shall be prima facie evidence of the nonexistence of such marriage.

SEC. 3.

From and after the date of the approval of this Act,
divorces in which a member of the said tribes or band of Indians is
a party shall be effected only by decree of a State court of competent
jurisdiction.

SEC. 4.

No person shall be entitled to inherit as the surviving
spouse of a deceased member of the Klamath or Modoc Tribes or Yahooskin
Band of Snake Indians by virtue of a marriage entered into subsequent
to the effective date of section 1 of this Act unless his or her
marriage to the decedent has been solemnized in conformity with the
provisions of this Act: Provided, That nothing herein contained
shall be construed to authorize the devolution of restricted property
within the Klamath Reservation to any person not qualified under the
provisions of section 5 of the Act of June 1, 1938 (52 Stat. 605).
